PURPOSE:To weld a bracket made of a thin sheet having smallheat capacity to an exhaust pipe without erosion and to prevent the fracture of the bracket in use by forming at least one hole to the bracket to be superposed on the exhaust pipe and welding the bracket to the exhaust pipe along the inside circumference of the hole. CONSTITUTION:Welding length is always equal to the inside circumferential length of long holes 2C, 2D or 2E; therefore, welding strength is maintained almost constant and the variation in each product is eliminated. Arc heat is further applied on the central part of a bracket 2 and is dispersed almost uniformly over the entire surface of the bracket 2, whereby the fracture of the bracket 2 owing to excessive heating is prevented. |
